Intel i7-6900K vs i7-6850K

The Intel Core i7-6850K @ 3.60GHz is newer than Intel Core i7-6900K @ 3.20GHz and is around -22% slower in multi-threaded (CPU Mark) testing. However the CPUs have comparable single-thread rating. Both CPUs operates at simliar power levels (TDP). All the CPUs in this comparison belong in the Desktop CPU Class. The values below were tabulated from a combined 2067 benchmarks submitted from our PerformanceTest software and results and are updated daily to include new submissions.

  • The first section will show basic information for each CPU selected.
  • The additional graphs shows the CPU Mark and Single Thread values of each CPU selected.
  • An accompany graph, if price data is available, will shows the value for money, in terms of the CPU Mark/Thread Rating per dollar.
  • The last section will show approximate yearly running costs for the CPUs.
